AUTOMATICALLY-GONTROLLED PAPER-CUTTER.

Specification of Letters Patent.

Patented Apr. 21, 191a.

Application'filed October 11, 1912. Serial No. 725,127.

To all whom it may concern Be it known that I, GEORGE J. NETH, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Automatically- Controlled Paper-Cutters, of which the following is a specification.

My present invention relates to an automatically controlled paper cutter, and it belongs to that class of paper cutters usually employed in stores and operated by hand, in which the paper used to wrap the article is severed or cut from the roll by being pulled or drawn against the cutting edge of a blade; bar or long knife.

Some of the principal objects of my invention consist in providing in a device for outtingwrapping paper from a roll by hand; means whereby said paper will be automatically fed to the operators hand, thereby dispensing with the objectionable feature of doing this part of the operation by hand, thus avoiding the slipping and crumpling of said paper and other disadvantages connected therewith.

Another object is to provide said device with means whereby the paper will be automatically and temporarily held, during the process of automatically feeding or delivering same to the operators hand.

Further objects are to provide a device for cutting wrapping paper, which will be more eflicient giving better results generally; that is composed of few parts; is simple in construction; and one which can be manufactured at a small cost and therefore is inexpensive.

This invention consists essentially, referring briefly and in general terms to the structure covering the device, of the very peculiar construction, arrangement and combination of the various mechanical parts or elements and the minor details thereof, all of which will hereinafter be fully and specifically described, and set forth in the subjoined claims all in accordance wlth the statutes in such cases made and provided therefor.

Referring to the accompanying drawings constituting a formal part of this specification, and illustrating one form of construction for carrying out the objects and principles of my invention, and wherein the same reference letters are utilized to indicate and point out the same parts wherever occurring throughout the several views F igure 1 is a front elevation of my auto matically controlled paper cutter,partlally broken away and showing the location of the paper roll in dotted lines; Fig. 2 is an end view of same. Fig. 3 is a broken away View of a portion of one of the side arms-as seen in Fig. 2,-but on an enlarged scale therefrom. Fig. 4 is a transverse sectional view of the cutting-bar. Fig. 5 is a detail view of a broken away portion of the cutting-bar and one of its hinges and shaft; and Fig. 6 is a perspective view of one of the hinges which connects the cutting-bar and its shaft.

In describing my said invention specifically, and referring in detail to the various parts or features of construction which in combination make up my automatically controlled paper cutter, as shownthroughout the several views of the drawings and indicated therein by means of the reference characters as aforesaid :A refers to the base provided near each end with a plate a, to each of which is detachably connected in an ordinary manner by a screw or otherwise, the foot I) of one of the standards B; while the top 0 of each of said standards is adapted to have detachably connected thereto by means of bolts,or in any ordinary and well'known manner,the top-rail or handrest O.

From the inner face of each standard B projects a semi-circular or U shaped flange d, each of which receives and supports one of the ends of the spindle or rod e,'see more particularly dotted lines in Fig. 2;- upon which is movably mounted the roll E of wrapping paper, by means of the usual bulsihing 6 located in each end of said paper ro Pivotally swung or supported from each standard B by its arms or ends f is an automatic brake-bar F, which constantly gravitates against roll E thus automatically helping to control the revolution of said roll and hold same stationary when not in operation.

Extending from each standard B is one of the side arms or supporting plates G, which is preferably connected thereto by means of its short extensions which are securely clenched over said standard as shown, and in this instance its lower end is adapted to rest in flange (Z; or it may be connected in any suitable manner; or if so desired each standard and its side arm may be formed integral. Said arms are each formed with a slot h.

The free end of the wrapping paper from roll E, passes over idle-roller H, the ends of which are journaled in side arms G; thence down and under another roller 70 against which it is held or temporarily locked by tension-bar Z, the shaft m of which is j ournaled and turns in the side arms G; one end of said shaft extending some distance beyond one of said side arms where it is provided with a short arm and weight L, as fully and clearly shown; by which said tension bar is automatically operated, and locks said paper between it and roller is until pulled by the operator when using same, when said weight being of just the proper heft will permit said tension-bar to move sufficiently to allow said paper to pass. Said paper after passing between roller is and tension-bar E, as just described; extends downward passing through the longitudinal slot at of cutting-bar N, terminating just a short distance beyond it, as fully and clearly shown in Figs. 2 and 3.

Cuttingbar N is constructed out of a suitable quality of metalpreferably a good grade of steel,-and is provided near the ends with a brace a and has its ends slidably jonrnaled at n in the slots k of the side arms G,see Figs. 2, 3 and Said cuttingbar is formed with a sleeve 0 which is cut away to receive the ears 1 of the hinges R, and through said sleeve and ears passes a rod 8 which connects said cutting-bar and said hinges, and upon which the ears turn. Hinges R are each also formed with a sleeve 1 through whicn passes a shaft or rod 75, the ends of which are journaled in the side arms G, and upon which sleeves r turn. in Fig. l the cutting-bar is shown as equipped with three hinges, but it is obvious that any suitable number of hinges may be employed, according to the size of the paper cutter, which may of course be manufactured in more than one size.

it will readily be understood that when it is desired to remove a piece or section of wrapping paper, it is only necessary to grasp the upper and lower face of said cutting-bar between the fingers and thumb, and push it from the lower and forward position to the upper and rearward position shown in dotted lines in Figs. 2 and 3, through the medium of slot h; when a sufficient amount of paper will be fed to the operators hand so that he can pull the desired amount away from the device by means of tension-bar l, as heretofore described,and as he releases his grasp on said cutting-bar it will gravitate again toits forward and normal position, when the paper can be quickly drawn against the upper or lower edge of slot 11. and be severed or cut ofi. It will be obvious that the upper and lower edge of slot n of said cutting-bar, are each adapted to sever or cut the paper when drawn against it, thus causing said cutting-bar to act as a double cutter.

Having now described my automatically controlled paper cutterin connection with the illustrations,as my invention and as new, I claim:

1. The combination in a paper cutter of the standards provided with side arms each formed with a slot; an idle-roller journaled in said side arms; a roller and tension-bar journaled in said side arms; and a cuttingbar journaled in said side arms and pro vided with a double cutting edge, and adapted to move backward and forward be tween said side arms; all substantially in the manner and for the purpose described.

2. The combination in a paper cutter, of the standards; the side arms each formed with a slot and projecting from said standards; an idleroller journaled in said side arms; a roller and a weighted tension-bar journaled in said side arms; and a cuttingbar provided with hinges and having its ends slidably journaled in the slots of said side arms; substantially as described.

8. In an automatically controlled paper cutter the combination of,a base, standards, and a top-rail; supporting plates each pro ided with a slot and extending from said standards; an idle roller journaled in said supporting plates; a roller and an automatic tension-bar journaled in said supporting plates; and a cutting-bar having a double cutting edge and slidably journaled in the slots of said supporting plates.

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE J. NETH.
